United States, and residents of St. Louis,A

Missouri, have invented certain newand useful ImprovementsinSwitch-Boxes', of: which the following is a specification This inventionrelates to improvements in switch boxes and has for its object a casingso constructed as to be connected one with the other so that any numberof electric switches may be properly inserted and that the series ofconnected boxes may be rigidly connected together and supported ,in thewall of a building.

A 'further objectv of our invention is to consti-uct a switchbox which.is provided with' adjustable ears and fastening devices by which anynumber' of boxes may be con nected together and that by the adjustable.ears the same can be propprly placed in position in new work'as we i asto accommo- .date the adjustment for repair 'worinV rihe essentialfeature of our invention is to construct avswitch box in sectionsso asto ladjust the saine to accommodate the insertion 'of various sizedyswltches as well as to extend the saine'to accommodate a series ofswitches, and to provide means whereby the vboxes can be used for newwor-kas well as to be properly adjusted and placed in proper positionwhen used for repair Work.

L In carrying outvour invention we provide a box consisting of a casing6 constructedof a single'piece of material comprising a top 7,

portion of oneA section being depressed as indicated by the vnumeral l0and is provided..

with internally screw-threaded botes il; the ed e 12 of the overlappingsection is pro- -vi ed with elongated slots 13 through which arrangedthat one section may readily' connected to the other and firmlyiieidthere to, yand when doing so the side portions l5. are removed so thatthe vcedriccting edge o the adjacent section may' be inserted inposition in its place.

By placing a number of the sections to l gether and in locked alinernentthe sarde be built up tol any length and. any number-- of switchesinserted side by side is ici/ind desirable and necessary.

in order to properly fasten or locs one section to the other, the'casings are constructed with eiongated' slots '16 torni-ed onA oneedge. and projecting hoolrs i7 'formed on the other and so arrangedthatone will co'- operate with the other and by slightly def-- pressing onesection, the hooks i? will seat themselves in the elongatedslots i@ andhold both sections iu' locked position; the upper edges of thecasings-are likewise constructed having .hooks i8 so shaped and bent asto seat themselves 'in elongated slots i9 formed in the upper edge ofthe communicating sec tion; after a number of sections have lbeen placedtogether the ends l5` are placed .to-` get hei to'compiete the casing,these-ends be ing provided with hoo@ 2() arranged torbe Q inserted inelongated slotsQl, and in addi 'tion to the hooks, a slottedear isprovided which overlaps the upper edge of the cas` ing and Which-is heldin pb'sition by a screw 23, and in order to 'provide rigidity to thecasing and to prevent thesame from spreading we provide on-one edge of-tiie'side's a projecting flange or hook 24; which-contacts,

the saine in a rigid position. 4 l The corners of the switch boxes aresuitA ably stamped cutting into the material ormwvting circularindentations still keeping the material intact, but so arranged thatthev said material may be removed by punchingA out vthe circles and saidcircles being-oic such size as to' permit the insertiono insulatedtubing through whichthewires are led into theswitch casing.

I switch box we provide adjustable ears 25 il (l used in new work, butthe same are so arranged and tapered that when the device is to be usedin connection `'with repair work the ears can be readily broken ofi atthe pointindicated by the numeral 31 assuming a. position as shownbydotted lines at'theleft in Fig. 2; the body portion to which the earsare connected is also perforated as indicated by the numeral 32 so thatsaid ears can be firmly attached to the studding by screws 'when theears 30 are disconnected.

The verticaly portion 27 has a portion of itself cut away/as indicatedby the numeral which provides for the projecting lug 34. formed on -theedges of the top 7 and bottom 8, and which are provided with internallyscie\\'tli1eaded. bores 35 to which is attached the switch which isinserted in the box.

In Fig.` 5 we show a modified form of box which in general constructionis identical with that previously described with the exception that theears are velongated and openings areformed in the top and bottom so thatcond uitsl 36 can be inserted and the box, or the sections forming thesame held in position by the' lock nuts 37 and bushings located on theinner side -of the conduit if so desired; through these conduits arepassed the electric wires and boxes of this construction are embedded inthe wall 'where the ap' plication ofsucli devices is found desirable andapplicable. i

lhe essential feature of `our invention is the eonstructionof a switchbox that by removing the end sections the box can be readily connectedtogether andextended to form any length desired and also-:ii'i'aiigefl'-iul-- justabefto extend the height thereof a reasonabledistance.'

Another feat-ure is that lby means ofthe adjustable ears the boxes can.be usedV for new worlcas wellasrepair work and can be readily adjusted'so thatthe front edge islin proper position. with'the plaster"lineofthe wall so that the face plate ofthe switch when attached to thedevice will be in proper i position on the wall.

firmly secured tobe located, substantially as specified.

Having fully described our invention what we claim is:

l. A switch box comprising a body poi'- tion consisting of two sectionsthe contacting. 05 edges arranged to overlap, the edges of the sides' ofsaid sections provided with hooks and slotswhereby one body portion lnaybe attached to the other; adjustable detachable` fastening deviceswhereby the box is secured in position against the wall, and elongatedprojectingfears radiating fronithe fastening member, substantially asspecified.r

I A device of the class described comprising a' switch box composed oftwo sections, the contacting edge olf eachfarranged to overlap, integralperforated lugs formedon the faceof each section, `a hook formed on theside edge of one section and a slot on the side edge of the companionsection, an adjustable-,detachable fastening member `provided withelongated slots and a pair of raf` dieting integral elongated ears whichearsf are adapted to be broken oif ias .desired de o pending on thepositionv inwhich the box is I .Y

3. An article of the class describedy c'om'- perising a. switchboxconsisting of" a'body' porticncomposed of two sectionsr ,they con- .ltact-ing edges arranged tok oveiila'jnA hooksi and slots arranged. inthe`sections wherebyy said sections may be ganged'together, detachablesides provided with hooks and'earsby whichy the sides are held in'placeagainst the box in combination with detachable ad-v justablefastening members having angular extending ears for holding the box invposition in the wall, theside ears-being'arranged to be broken ofi whennot desired yet keep-v ing the fastening member intact, substan-4 '100,

tially as speciiied.

4. A switch box lcomprising a body4 por-l* tion consisting of v twomembers the contact edges arranged to overlap, a pair `of Iadjiistl.y

able detachablefasteningmembers located 10.5 on theupper andV lowerlsides of the bodyy portion, said fastening'- members havingY f pair ofelongated fastening slots byiwliiclif the same isy adjusted inlposition` and".right-` angular section forming apart of the fastenllOing member; and a pair of `elongated pr`0"A jecting ears formed on theangular"fexten-v4 sion', substantially Aas spe'ciiied.F i
